Saskatoon berry juice for faster muscle recovery after intense exercise.
Official title: Effect of Short-term Saskatoon Berry Supplementation on Muscle Recovery
Run by University of Saskatchewan · NCT07433686 · Data updated 2026-11-12
This will see if drinking 375 ml of Saskatoon berry juice daily helps healthy 18–35-year-olds recover strength and have less soreness after an intense biceps workout.

Is this trial a fit for you?
✓Likely a good fit
Healthy men and women aged 18–35 who can attend in-person visits, drink the study beverage daily, and complete the intense biceps exercise protocol are ideal candidates.
✕Probably not a fit
People over 35, individuals with medical conditions that limit safe exercise, or those unable to attend the on-site exercise and follow-up visits are unlikely to benefit.

What this trial studies
Saskatoon berries are rich in polyphenols that have anti-inflammatory and antioxidant effects and may protect muscle from exercise-induced damage. In this randomized, placebo-controlled trial, 30 healthy adults aged 18–35 will drink 375 ml of Saskatoon berry juice or a placebo daily for 10 days. On day 7 participants complete six intense biceps-curl sets and investigators measure isometric strength, muscle swelling, and soreness before, immediately after, and at 24, 48, and 72 hours post-exercise. Recovery patterns between the juice and placebo groups will be compared to see if the juice speeds strength recovery and reduces swelling and soreness.
Why it matters
Potential benefit: If effective, the juice could shorten recovery time and reduce muscle swelling and soreness after intense exercise.
How similar studies have gone: Studies of other polyphenol-rich berry juices, such as tart cherry, have sometimes shown reduced soreness and faster recovery, but clinical data specifically on Saskatoon berry juice are limited.
